A new triazine-cored covalent organic polymer for catalytic applications

A triazine based covalent organic polymer (CC-TAPT-COP) was designed and synthesized via nucleophilic substitution reaction between 1,3,5-tris-(p-aminophenyl) triazine and cyanuric chloride under refluxing conditions with bottom-up approach. The structural and morphological properties of CC-TAPT-COP were well characterized by various spectroscopic and analytical techniques. The CC-TAPT-COP appeared as an irregular block morphology (SEM) and possesses remarkable thermal stability. The physical properties such as insolubility, chemical and thermal stability of CC-TAPT-COP provide a sustainable alternative to classical metal-assisted and homogeneous catalysts. In this report, we have explored CC-TAPT-COP as a heterogeneous catalyst for expedient access to the substituted quinazoline, a family of N-containing biopharmaceutical active heterocyclic compounds, at ambient conditions. Moreover, the present work not only supports COPS for their synthesis, but also paves an opportunity for catalytic applications as heterogeneous media.
